MC22 - Elizabethan Silk Organza Partlet Pattern. Multiple options: the partlet goes over the corset which is over the square necked chemise. The base of the partlet has a casing with a drawstring that can be adjusted so that there is an inverted "V" opening. There is also a strip of silk with lace on the edge that is pinned to the top edge of the corset , this create the key hole opening. The bodice would go over all and would come about 1 to .5 inches from the bottom lace.
